Descriptions

1.High efficiency crystalline silicon solar   cell. Even if under the weak light, the solar module can produce maximum   power output.

2.Tempered glass (toughened glass):   Anti-reflecting coating and high transmission rate glass increase the power   output and mechanical strength of solar module.

3. EVA and TPT: Using high quality EVA and   TPT to prevent destroying and water.

4. AI frame: Without screw, rner   connection. 6 holes on the frame can be installed easily.

5. Junction box: Multi function junction   box with water proof.

6. Long lifetime: ≥25 years; Less power   decrease.

7. Good performance of preventing from   atrocious weather such as wind and hails.

8. Resisting moisture and etching   effectively, not effected by geology.

9. The certificate issued by international   authority: UL, TUV, IEC, CE.

5. FAQ:

We have organized several common questions for our clientsmay help you sincerely

1). What’s price per watt?

A: It’s depends on the quantity, delivery date and payment terms of the order. We can talk further about the detail price issue. Our products is high quality with lower price level.

2). Can you tell me the parameter of your solar panels?

We have different series of cells with different power output, both from c-si to a-si. Please take our specification sheet for your reference.

3). How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.

4).Can you do OEM for us?

Yes, we can.

Q:Solar Battery System?
Deep Cycle Series batteries are designed to have a large amount of stored current discharged between charging sessions, with very heavy non-porous battery plates to withstand repeated major discharging and charging cycles (deep cycles). They are typically used where the battery is discharged to great extent and then recharged.

Q:Solar Energy Panels, a good idea?
It okorder.com/
Q:260 watt solar panels on an rv?
It depends on the power you need. There should be a controller between the battery and the solar pv panels.
Q:I have a 6v solar panel , but a 3v dc motor doesn't run with that!!!!?
BECAUSE IT COULD ENOUGH SUPPORT ENOUGH CURRENT, VOLTAGE DROPS DOWN NEAR V WHILE OVERLOADED WITH MOTOR. BUY A VERY LARGE SIZE SOLAR CELL WILL FIX IT.
Q:Need help with a solar panel?
In order: .  Just about any wire will do.  You can handle 50 mA over just about anything, even 28 gauge telephone wire.  Your biggest problems are probably going to be mechanical stress (you want stranded wire instead of solid, to avoid breakage) and dealing with the size of larger wires. 8 gauge speaker wire may be a good optimum. 2.  You need a diode.  If you're charging NiMH or NiCd cells you're going to have about .25 volts/cell; you can charge up to 3 of them in series with a 4.8 volt panel.  The solar panel is a bunch of diodes itself, but they're leaky in the reverse direction; the diode prevents the batteries from discharging themselves back through the panel.  You want a Schottky-barrier diode, because the forward voltage drop is about 0.2 volts instead of 0.7 volts for a regular silicon rectifier.  This gives you maximum current output from your panel.
Q:how to build solar panels?
i think the evil Genius book has how to build home made solar cells.
Q:How to make electricity from the sun without using solar panels?
Solar cells are the cheapest way to produce electrical energy directly from the sun at this time. All other methods are experimental and not something the average person would ever want to use. If you are an engineer with a background in designing you might be able to pull it off but odds are you are going to spend a lot of money doing development work and not produce much power. It is possible to build you own hot water collectors to provide your domestic hot water. It is a lot of work but if you don't have the money to purchase the collectors it is an option.
Q:Solar panel question..?
Little solar panels on lights are very low power. The battery in one such may be 0.5 Amp-hours and .2 V ; it may be different but it should be marked on the panel/battery/manual. An outlet in your house is designed to run on 20 V (typically in N. Am.) and they run on alternating current (AC) whereas the panel generates direct current (DC). (If you don't know the difference, do not worry to much but just understand that they are not directly compatible.) You therefore need an inverter to change DC to AC (and lose some although inverters are now very efficient). But the amount of power generated by those panels is still very small. That is why solar lights are low power (just a few watts in most cases). To make things even more irritating, phone chargers do not work off 20 V AC as you are charging the battery and need a low voltage DC -- which is what the solar panel is giving you. It is almost certain that the voltage from the panel will be less than the voltage required for the phone. The charger is mostly cable but there is a black box incorporated and it should say what the voltage and current output are (the input will be 20V). So you should be able to overcome this not by hooking up the panel to a 20V outlet and then plugging the charger in but by hooking up the panel to the phone directly if you can get enough voltage out of the solar panel (or hook up several) and if you fashion a connection device. They already make them -- solar battery chargers and I am sure you can enter that into a search engine and find loads. Typically the panel alone is much more than a solar light -- which shows the relative power requirements.
Q:Life expectancy of LEDs and Solar panels...?
LEDs last approximately 50,000 hours of operation, continuous or non-continuous, it doesn't matter. 50,000 hours. Solar panels will, theoretically, last until the end of time. The support structures will fail long before the panels themselves. Inverters, battery banks, op-amps, transformers, control boards, etc. will all fail long before a solar panel stops making juice.
